Plectrum

For hand-held instruments such as guitars and mandolins, the plectrum is often called a pick and is held as a separate tool in the player's hand.

[citation needed] For other instruments in the modern day, most players use plastic plectra but a variety of other materials, including wood and felt (for use with the ukulele) are common.

The plectra for the Japanese biwa and shamisen can be quite large, and those used for the Arabic oud are longer and narrower, replacing the formerly used eagle feather.

[2] In late French harpsichords by the great builder Pascal Taskin, peau de buffle, a chamois-like material from the hide of the European bison, was used for plectra to produce a delicate pianissimo.

[7] As the plectrum is progressively trimmed, its jack is replaced in the instrument at intervals to test the result for loudness, tone quality, and the possibility of hanging.

Voicing is a refined skill, carried out fluently by professional builders, but one that usually must also be learned (at least to some degree) by harpsichord owners.

Plectra is used in formal writing, particularly in discussing the harpsichord as an instrument of classical music,[13] while plectrums is more common in ordinary speech.
